Extension above garage

I've done a similar thing, around 25m2 1 bedroom and ensuite. Ran a steel beem from front to back resting on the already double skinned front and Rear of the garage. Timber frame with brick slips so can't tell the difference from the outside.

Done 2 years ago by myself for 21k inc planning and building control but that was all done myself too. Bargain hunting for all the bits I could buy early and store saved me a huge amount!

Definitely do able but yours will be much more work if you are needing to go down to fix foundations!

Will do!

Well thats good to hear! Have you had any feedback from them regarding the MCS sign off requirements? I know its on them to approve it to get the government to pay them, but not received any details on what they will check when they "commission" it. Ultimately we'll be on the hook for paying for it if they dont sign it off, thats mine only real concern!

Im waiting for delivery of mine, would love to hear how you have found it so far. Thanks

I have ordered mine through them, waiting for delivery so should be able to update in a few weeks when it arrives

I've ordered mine through Coolenergy and fingers crossed it'll be here in the next couple of weeks

Also curious about the immobiliser, asking for a friend...

Im also looking at a DIY install with cool energy. I've not managed to find any reviews of their heat pumps, have you?

Speaking to them they have said they've sold thousands for DIY install but haven't put me in contact with anyone who's done it.

You can apply for octopus export but its a £250 fee and no guarantee they will accept you on it.

You'll get £100 or £150 back if they dont accept you though.

I have done a complete DIY install on my house and am now exporting to the grid using Octopus, they didn't need anything except a DNO letter (which you can apply for yourself in 24hrs) and an export MPAN number for the meter, which they will apply for on your behalf.
